What is level sensor?
A Level sensor is a device that helps to measure the level of a liquid or bulk solid material in a container or system. It offers continuous level measurement and point level detection through contact or non-contact methods. Level sensors are commonly employed in various industries to ensure the safe and efficient operation of process control and automation systems.
Level sensor types
According to the principle of level sensor operation, level sensors can be categorized into several types:
- Radar level sensor
- Ultrasonic level sensor
- Capacitive level sensor
- Point level sensor
- Hydrostatic level transmitter
- Magnetostrictive level transmitter
Level sensors are versatile and can be employed for various applications, such as water tank level measurement and powder level measurement. Furthermore, level sensors can be further categorized into contact level sensors and non-contact level sensors based on their level detection methods.
